UnDBX is a tool to extract, recover, and undelete email messages from Outlook Express .dbx files. On first run, all messages are extracted as individual .eml files. Subsequent runs only update the output directory with new messages, and delete old .eml files that correspond to deleted messages in the .dbx file. Corrupted .dbx files (including files larger than 2GB) can be opened in recovery mode, in order to recover messages and partially undelete deleted messages. The success of recovery depends on the type and level of .dbx file corruption.

PhotoRescue will undelete, unerase, and recover pictures, images, and files lost on corrupted, erased, or damaged compact flash, smartmedia, memory sticks, mmd, XD, multimedia, or secure digital memory cards when other solutions fail. It supports the recovery of all file types, but its algorithms are particularly optimized for JPEG files, TIFF files, GIFs, and BMPs. It also offers constantly updated support for CRW, NEF, ORF, MRW, and many types of movie files. In some cases, it can even rebuild pictures that have suffered minor corruptions. It deals with cases where the media is not visible as a drive letter anymore. The unique unfragmenting technology rebuilds cherished memories that would otherwise have been lost forever.
